Authenticated Emails

MailerMailer uses SPF and DKIM technologies to authenticate your emails. ISPs look for these digital fingerprints on incoming emails to make sure they are legitimate
messages, sometimes discarding the ones that are not authenticated. This dramatically reduces the likelihood of your messages being blocked.

ISP Feedback Loops

We maintain positive relationships with all of the major ISPs. Our long-standing whitelisting agreements and feedback loops with them allow us to keep complaint rates
low while keeping deliverability high.

A Reputation You Can Trust

MailerMailer has one of the highest SenderScore deliverability rates in the industry. SenderScore, a third-party email reputation monitoring service by ReturnPath,
reports that 99% of messages from our servers reach the inbox — a solid reputation that you can trust.
